I often want to make a multiline function call and reduce it down to one line. For example, convert...
function_call( 'first_arg', 'second') to
function_call('first_arg', 'second') Does emacs have some commands to help with this. Specifically, is there a command that will delete all whitespace from the point to the first non-whitespace character?

Move your cursor directly before the region you want to delete. Set a mark by pressing Ctrl-6 or Ctrl-^ . Move the cursor to the end of the region you want to delete and press Ctrl-k .
To delete trailing whitespace from the entire buffer, use 'M-x delete-trailing-whitespace' .
Emacs provides many ways to delete text. The simplest way to delete text is to press the DEL key, which deletes the character immediately to the left of the cursor. See Figure 2-3 for possible locations of the DEL key on your keyboard. DEL is easiest to define by what it does: it deletes the previous character.
You might try delete-indentation, my favorite command for joining multiple lines into one line. In your example, put the cursor on the line with "second" and hit M-^ twice. Here are the docs:
M-^ runs the command
delete-indentation, which is an interactive compiled Lisp function insimple.el.It is bound to M-^.
(delete-indentation &optional arg)Join this line to previous and fix up whitespace at join. If there is a fill prefix, delete it from the beginning of this line. With argument, join this line to following line.
